A sheltering device configured for being installed over a designated object such as a vehicle's roof. The sheltering device includes: a single flexible cover having a shape of varying width; foldable supporting arms, attachable to the cover; and a retractable mechanism configured for folding and unfolding the foldable supporting arms for folding and unfolding the cover. The foldable supporting arms are configured to simultaneously move along predefined non-parallel trajectories when unfolding, to allow the flexible cover, attached thereto, to unfold in a forward and sideways movement throughout the unfolding movement, while creating two (or more) stable supporting points suspended in air at its distal edges and/or along the bars, which provide tension to the cover attached in all required direction, thus eliminating the necessity of using a ridged connection between these distal edges. |

1. A sheltering device configured for being installed over a designated object for providing shelter in the vicinity of said object, said sheltering device comprising:
at least two foldable supporting arms, wherein each of said at least two foldable supporting arms comprises a first set of bars and a second set of bars, interconnected by hinges constructing scissor mechanism; a single flexible cover attached to each of said at least two foldable supporting arms by at least one point; and a retractable mechanism configured to fold and unfold said at least two foldable supporting arms for folding and unfolding said single flexible cover attached thereto; wherein a first bar of the first set of bars, which is associated with said retractable mechanism, is slightly longer than a first bar of the second set of bars, wherein each of said at least two foldable supporting arms is supported only at one proximal end thereof by the object, such that each of the at least two foldable supporting arms creates at least one stable supporting point suspended in air at a distal arm tip; wherein said at least two foldable supporting arms are configured to simultaneously move along a two dimensional travel course, the at least two support arms moving along a first axis and a second axis respectively, the first axis and the second axis defining non-parallel trajectories such that farthermost tips of the at least two foldable supporting arms move away from one another when unfolded, to allow said single flexible cover, attached thereto to unfold in a forward and sideways movement in a two dimensional travel course throughout and according to the travel course movement of the at least two foldable supporting arms, and wherein a distance between the farthermost bar tips of said at least two foldable supporting arms is significantly larger in an unfolded state of the single flexible cover than a distance between said farthermost tips in a folded state of the single flexible cover. |
